Thursday marks the second annual "National Unfriend Day," which Kimmel is sponsoring to encourage Facebook users to delete anyone who isn't actually their friend. Kimmel says millions of Facebook friends were deleted during last year's "National Unfriend Day."

"Half of the the people in this country are on Facebook and many of those people have hundreds, if not thousands of friends," Kimmel told the Jimmy Kimmel Live audience last week. "I find this unacceptable that no one has thousands of friends ... If you have ten friends in your life then you're doing very well."

Kimmel may be a comedian, but he does have a point. Most of us are guilty of never actually speaking to the majority of our Facebook friends. We may have "friends" who pop up on our News Feed every so often, but we can't seem to recall how or even if we know them.

So what do we do with these acquaintances, and in some cases, strangers? Kimmel's advice: Cut anyone who isn't actually your friend.

If you can't decide whether to unfriend someone, check out this video to hear Kimmel's point system that will help you decide who stays and who goes.

Will you unfriend your Facebook "friends" today? Let us know in the comments.
